Staged Deployment for Electrical Charge Spots

ABSTRACT

A method and system is provided to deploy electrical charge spots in stages according to demand. During a first stage a plurality of infrastructure adapters are installed. This may involve demolishing and rebuilding portions of the infrastructure and laying down power cables from the electrical power supply to the charge spot locations. The infrastructure adapters are then coupled to an electrical power supply. Many if not all of the infrastructure adapters are covered with a temporary housing protecting them from vandalism and weather. During a second stage, in response to a demand for charge stations, the charge stations are completed. During the second stage, at least one external unit is attached to an infrastructure adapter by making an infrastructure adapter quick connect interface with an external unit quick connect interface. As such, a charge spot is completed quickly in response to demand.

BACKGROUND

Vehicles (e.g., cars, trucks, planes, boats, motorcycles, autonomousvehicles, robots, forklift trucks, etc.) are an integral part of themodern economy. Unfortunately, fossil fuels, like gasoline which istypically used to power such vehicles, have numerous drawbacksincluding: a dependence on limited sources of fossil fuels; foreignsources of fossil fuels are often in volatile geographic locations; andsuch fuels produce pollution and likely climate change. One way toaddress these problems is to increase the fuel economy of thesevehicles. Recently, gasoline-electric hybrid vehicles have beenintroduced, which consume substantially less fuel than their traditionalinternal combustion counterparts, i.e., they have better fuel economy.However, gasoline-electric hybrid vehicles do not eliminate the need forfossil fuels, as they still require an internal combustion engine inaddition to the electric motor.

Another way to address this problem is to use renewable resource fuelssuch as bio-fuels. Bio-fuels, however, are currently expensive and yearsaway from widespread commercial use.

Yet another way to address these problems is to use clean technologies,such as electric motors powered by fuel cells or batteries. Thesebatteries need to be recharged relatively often. For example they mightrequire re-charging in a parking garage of a store or office building.Therefore, many charge stations may be required. As more and morevehicles use rechargeable fuel cells or batteries, more and more chargespots will be necessary. However, connecting each charge spot to anelectric power grid can be costly and time consuming. Furthermore, thedeployment often requires an operator with specialized skills.Similarly, if the charge spot malfunctions or is vandalized, replacementof the charge spot is also costly, time consuming, and requiresspecialized operator skill.

It would be beneficial if there were a system that could quickly deploymore charge spots as demand grows. It would also be beneficial if thedeployment did not require an operator with specialized skills.Furthermore, it would be beneficial if charge spots could be quickly andeasily replaced when necessary.

SUMMARY

The following presents a summary of the invention in order to provide abasic understanding of some of the aspects of the invention. Thissummary is not an extensive overview of the invention. It is notintended to identify key/critical elements of the invention or todelineate the scope of the invention. Its sole purpose is to presentsome of the concepts of the invention in a simplified form as a preludeto the more detailed description that is presented later.

In order to overcome the above described drawbacks, a network of chargespot infrastructure adapters is deployed during a first stage. Thisfirst stage involves connecting the infrastructure adapters to a mainpower grid, which may include removing walls, digging, etc. Then in someembodiments, many of the adapters are covered for protection until theyare required. During a second stage at least some of the infrastructureadapters are coupled to external units to create complete charge spots.As the demand for charge spots increases, more external units arecoupled to the infrastructure adapters. The adapter includes aninterface that easily mates an interface on the external units. Theinterfaces are universal such that any external unit can be mated to anyadapter. Thus, the system can easily expand in response to demand untilall of the adapters have been connected to external units. Furthermore,because of the universal interfaces, the external units are quick andeasy to install and replace.

Specifically, the present invention overcomes the limitations anddisadvantages described above by providing methods and systems fordeployment of an electrical charge spot system for charging at leastpartially electric vehicles in stages.

Some embodiments further provide communicatingthe unique geographic ID to a service provider.

In some embodiments, the method further comprises during a third stage,temporarily coupling a vehicle charging interface portion of the carelectrical connector to an at least partially electric vehicle andenabling power to flow from the power supply to the vehicle through thepower supply electrical interface, the adapter quick connect interface,the external unit quick connect interface, and the car electricalconnector.

In some embodiments, the method further comprises during a third stage,communicating charging information associated with the power flowingfrom the power supply to the electric vehicle, from the charge spotsystem to a service provider, via the power supply electrical interface.Alternatively, in some embodiments, the method further comprises duringa third stage, communicating charging information associated with thepower flowing from the power supply to the electric vehicle, from thecharge spot system to a service provider, via a wireless communicationdevice in the charge spot system.

In some embodiments, the method further comprises during a third stage,replacing the respective external unit with a new external unit, bydecoupling the external unit quick connect interface of the respectiveexternal unit from the adapter quick connect interface of the respectiveinfrastructure adapter, and removably coupling an external unit quickconnect interface of the new external unit to the adapter quick connectinterface of the respective infrastructure adapter. In some embodiments,the third stage also comprises communicating a unique geographic ID fromthe infrastructure adapter to the new external unit.

In some embodiments, the method further comprises during a third stage,installing one or more additional external units by removably couplingone or more external unit quick connect interfaces of the one or moreadditional external units to one or more adapter quick connectinterfaces of previously unused infrastructure adapters of the one ormore infrastructure adapters. In some embodiments, the third stageoccurs in response to an increase in demand for charge spots.

In some embodiments, the second stage installing includes installing acharge spot shell. In some embodiments, the first stage installingincludes covering the infrastructure adapter with a temporary housing.

Some embodiments provide an electrical charge spot system having one ormore charge spots for charging an at least partially electric vehicle.The charge spots include an infrastructure adapter configured toremovably connect to an external unit. The infrastructure adaptorincludes memory storing information related to the geographic locationof the infrastructure adapter, an adapter quick connect interface, apower supply electrical interface, and a data connector. The adapterquick connect having power connectors, data connectors, and a signalinginterface configured to communicate the information to the externalunit. The power supply interface is electrically coupled to the powerconnectors and configured to be coupled to an external power supply. Thedata connector is electrically coupled to the data connectors andconfigured to be coupled to a data network. The external unit includesan external unit quick connect interface configured to removably connectto the adapter quick connect interface, and a car electrical connectorelectrically coupled to the external unit quick connect interface andconfigured to temporarily connect to and charge an at least partiallyelectric vehicle.

The external unit is removably mated to the infrastructure adapterthrough their respective quick connect interfaces. In some embodiments,the electrical charge spot system includes the at least one charge spotthat is mounted to a wall, a ceiling, or a floor.

In some embodiments, the infrastructure adapter is configured to becoupled to the power supply according to location specific requirementsof an infrastructure. But the external unit is generic and is configuredto couple to the infrastructure adapter without regard to the specificpower supply requirements of the infrastructure.

In some embodiments, the electrical charge spot system includes anadapter guide mechanism and an adapter tolerance mechanism in theinfrastructure adapter. Similarly, the external unit includes anexternal unit guide mechanism and an external unit tolerance mechanism.

Some embodiments provide an electrical charge spot system comprising oneor more charge spots for charging an at least partially electricvehicle. At least one charge spot comprises an infrastructure adapterand an external unit. The infrastructure adapter comprises a means forremovably mating to an external unit and a means for coupling to a powersupply. The external unit comprises a means for temporarily connectingto and charging an at least partially electric vehicle, and a means forremovably mating to the infrastructure adapter.

The advantages of the above described embodiments are numerous. Becausethe infrastructure of deployment can vary drastically from region toregion (e.g. there are different deployment practices and localregulations in different countries), deploying charge spots as entireunits would require developing units specific to the infrastructure inwhich they are deployed. However, according to the above embodiments,only the relatively simple infrastructure adapter needs to be speciallydesigned to comport with the infrastructure. Then the more complicatedexternal device can be a standard component that will easily mate withany infrastructure adapter. As such, the external units can be massproduced to cut down on manufacturing costs. Furthermore, the interfacesbetween the infrastructure adapter and the external unit are easy toplug into mate together interfaces. They do not require wiring toconnect to each other. A relatively un-skilled operator can deploy theexternal units, and need not use any particular tools save for a simplescrewdriver to install an external unit onto an infrastructure adapter.

Additionally, installing infrastructure adapters may require skilledoperators to install them. Limiting the number of hours spent by skilledoperators is therefore desirable. Infrastructure adapter installationmay also require relatively drastic changes to the installation site,such as excavating, installing a conductor in a trench, placing thefoundation etc. As such, limiting the number of times that theinstallation site must be disturbed is highly desirable. Using themethods described herein, a plurality of infrastructure adapters can beinstalled simultaneously, which cuts down on skilled operator time aswell as limiting the time that an infrastructure is disturbed. In fact,it is desirable that more infrastructure adapters are installed thanwould be necessary for currently needed charge spots. As such, only someof the infrastructure adapters will be connected to external units tomake functioning charge spots. The remaining infrastructure adapterswill be covered with a temporary housing. At a later date, theseinfrastructure adapters will be uncovered and attached to additionalexternal units. Installing these additional external units does notaffect the already functioning charge spots. As such, more charge spotscan be easily and inexpensively added as demand for charge spotsincreases.

DESCRIPTION OF EMBODIMENTS

Reference will now be made in detail to embodiments, examples of whichare illustrated in the accompanying drawings. In the following detaileddescription, numerous specific details are set forth in order to providea thorough understanding of the present invention. However, it will beapparent to one of ordinary skill in the art that the present inventionmay be practiced without these specific details. In other instances,well-known methods, procedures, components, circuits, and networks havenot been described in detail so as not to unnecessarily obscure aspectsof the embodiments.

FIG. 1 illustrates an electric vehicle network 100, according to someembodiments. The electric vehicle network 100 includes a vehicle 102 anda battery 104. In some embodiments, the battery 104 includes any devicecapable of storing electric energy such as batteries (e.g., lithium ionbatteries, lead-acid batteries, nickel-metal hydride batteries, etc.),capacitors, reaction cells (e.g., Zn-air cell), etc. In someembodiments, the vehicle 102 includes an electric motor 103 that drivesone or more wheels of the vehicle. In these embodiments, the electricmotor 103 receives energy from a battery (e.g., the battery 104) that iselectrically and mechanically attached to the vehicle (shown separatefrom the vehicle for the ease of explanation).

In some embodiments, the battery 104 of the vehicle 102 can be chargedat a charge spot 106, also known as a charge station. In someembodiments, the charge spots 106 provide energy to the vehicle tocharge the battery 104 of the vehicle 102. Charge spots 106 can beplaced at locations where vehicles may be parked. For example, thecharge stations can be located in parking lots of office buildings orshopping centers and/or near street parking spots. In some embodiments,a charge spot 106 can be located at a home of a user. In someembodiments, the charge spot 106 may charge the battery 104 of thevehicle 102 at different rates. For example, the charge spots 106 maycharge the battery 104 of the vehicle 102 using a quick-charge mode or atrickle charge mode.

In some embodiments, the battery 104 of the vehicle 102 can be exchangedfor a charged battery at one or more battery exchange stations 108.Thus, if a user 110 is traveling a distance beyond the range of a singlecharge of the battery 104 of the vehicle, the spent (or partially spent)battery can be exchanged for a charged battery so that the user cancontinue with his/her travels without waiting for the battery to berecharged.

In some embodiments, the vehicle 102 includes a communication module114, including hardware and software, that is used to communicate with aservice provider 112 of a vehicle-area network. Note that the term“vehicle-area network” is used herein to refer to a network of vehicles,batteries, battery exchange stations, charge stations, and a datanetwork.

In some embodiments, the service provider 112 obtains information aboutthe vehicles and/or the charge spots 106 and battery exchange stations108 by sending queries through a data network 120 to the vehicle 102,the charge spot 106, and/or the battery exchange station 108. Forexample, the service provider 112 can query the vehicle 102 to determinea geographic location of the vehicle and a status of a battery of thevehicle. Similarly, the service provider 112 can query the charge spot106 (and/or the battery exchange station 108) to determine the status ofthe charge spot 106 (and/or the battery exchange station 108).Similarly, the service provider 112 can query the battery exchangestation 106 to determine the status of the battery exchange station 106.

The service provider 112 can also send information and/or commandsthrough the data network to the vehicle 102, the charge spot 106, and/orthe battery exchange station 108. For example, the service provider 112can send information about a status of an account of a user, thelocations of battery service stations, and/or a status of the batteryexchange stations.

The electric vehicle network 100 shown in FIG. 1 also includes the datanetwork 120 and a power network 140.

The data network 120 may include any type of wired or wirelesscommunication network capable of coupling together computing nodes. Thisincludes, but is not limited to, a local area network, a wide areanetwork, or a combination of networks. In some embodiments, the datanetwork 120 is a wireless data network including: a cellular network, aWi-Fi network, a WiMAX network, an EDGE network, a GPRS network, anEV-DO network, an RTT network, a HSPA network, a UTMS network, aFlash-OFDM network, an iBurst network, and any combination of theaforementioned networks. In some embodiments, the data network 120includes the Internet.

As illustrated in FIG. 1, the data network 120 is coupled to the vehicle102, the service provider 112, the charge spot 106, and the batteryexchange station 108. Note that for the sake of clarity, only onevehicle, one battery, one charge station and one battery exchangestation is illustrated, but the electric vehicle network 100 may includeany number of vehicles, batteries, charge stations, and/or batteryexchange stations, etc. Furthermore, the electric vehicle network 100may include zero or more battery exchange stations. For example, theelectric vehicle network 100 may only include charge spots 106. In someembodiments, any of the vehicle 102, the service provider 112, thecharge spot 106, and/or the battery exchange station 108 includes acommunication module that can be used to communicate with each otherthrough the data network 120.

The power network 140 can include power generators 156, powertransmission lines, power substations, transformers, etc., whichfacilitate the generation and transmission. The power generators 156 mayinclude any type of energy generation plants, such as wind-poweredplants 150, fossil-fuel powered plants 152, solar powered plants 154,biofuel powered plants, nuclear powered plants, wave powered plants,geothermal powered plants, natural gas powered plants, hydroelectricpowered plants, and a combination of the aforementioned power plants orthe like. The energy generated by the one or more power generators 156may be distributed through the power network 140 to charge spots 106,and/or battery exchange stations 108. The power network 140 can alsoinclude batteries such as the battery 104 of the vehicle 102, batteriesat battery exchange stations, and/or batteries that are not associatedwith vehicles. Thus, energy generated by the power generators 156 can bestored in these batteries and extracted when energy demand exceed energygeneration.

FIG. 2 illustrates a charge spot 106 in accordance with some embodimentsof the invention. The charge spot 106 includes a shell 204 with one ormore vehicle charging interface 206 for connecting the charge spot 106to the vehicle 102 to charge the battery 104. In some embodiments thevehicle charging interface 206 includes a data communication interface,while in other embodiments it includes only a power interface. In theembodiment shown in FIG. 2, the vehicle charging interface 206 is anoutlet designed to interface with a detachable cable. In otherembodiments, the vehicle charging interface 206 includes a cable that ispermanently attached to the charge spot 106. In some embodiments, thecharging interface 206 also includes actuators for locking an insertedcable into the charging interface 206. It should be noted that thecharge spot 106 of FIG. 2 is a pole style charge spot, which is mountedto the floor, sidewalk, or ground and houses a variety of internalcomponents. In other embodiments, the charge spot 106 is a wall mounteddevice or a ceiling mounted device. In other embodiments, the chargespot 106 is a free standing device having a different configuration thanthe charge spot shown here, such as a box, or a box device located onthe top of a pole similar to a parking meter. The charge spot 106 issecurely mounted or attached to the ground, a floor, wall, or ceilingsuch that the charge spot 106 is not easily tampered with or vandalized.The embodiment shown in FIG. 2 includes a plurality of mounting elements202 to secure the charge spot 106 to the ground or floor.

FIG. 3 is an overview of the components of a charge spot 106, includingan infrastructure adapter 302 and an external unit 304 in accordancewith some embodiments of the invention. In FIG. 3, the external unit 304is illustrated slightly unplugged from the infrastructure adapter 302 inorder to illustrate how the two components would join together,according to the arrows. However, in a fully installed and operatingcharge spot 106, the external unit 304 and the infrastructure adapter302 would be mated together. In this embodiment, the infrastructureadapter 302 and the external unit 304 are both above ground and coveredby an external shell 204. In other embodiments, the infrastructureadapter 302 is located flush with the ground or wall such that theexternal shell 204 covers only the external unit 304. The details of theinfrastructure adapter 302 are explained with reference to FIG. 4. Thedetails of the external shell 304 are explained with reference to FIGS.5A-5B.

FIG. 4 illustrates an infrastructure adapter 302 of a charge spot 106 inaccordance with some embodiments of the invention. The charge spot 106comprises two distinct components, which are the infrastructure adapter302 and the external unit 304. In some embodiments, these two componentsare installed at different times, as will be explained in more detailwith respect to FIGS. 6A-6D.

The infrastructure adapter 302 includes a power supply electricalinterface 402 for interfacing with the external infrastructure. Thepower supply electrical interface 402 includes one or more powerconnectors 404 that interface with an electrical power supply 406. Insome embodiments, the electrical power supply 406 is localized such as alocal generator, but in most embodiments the power supply 406 is (or isconnected to) a local power grid or network 140 (FIG. 1) powered by avariety of power generators 156 (FIG. 1). It should be noted thatvarious countries and regions have different practices for electricalpower supplies 406, and therefore the power connectors 404 of theinfrastructure adapter 302 are adapted to conform to the particularrequirements of the local power supply to which it is attached.Similarly, in some embodiments, the power supply electrical interface402 also includes wired (or wireless) data connectors 408 that connectto a data network 120. The data connectors 408 are likewise adapted toconform to the particular requirements of the local data network 120. Insome instances data may be communicated over the power connectors 404using Power line communication or power line carrier (PLC), also knownas Power line Digital Subscriber Line (PDSL), mains communication, PowerLine Telecom (PLT), Power Line Networking (PLN), or Broadband over PowerLines (BPL) technology.

The physical specifications of installation site will also vary fromplace to place. Thus, the infrastructure adapter 302 includes one ormore physical connection elements 412 that interface with the particularsetting 414. For example, some infrastructure adapters 302 are installedoutside on the street or in a parking lot. Other infrastructure adapters302 are installed inside in parking garages or structures. Differentparking structures vary, with some having round pillars, rectangularpillars, sloping walls, etc., each of which may require a particulartype of physical connection element 412 (such as a bracket or fastener).Furthermore, as described with respect to FIG. 2 there are various typesof charge spot 106 configurations such as pillar charge spots, wallmounted charge spots, and ceiling mounted charge spots that may eachrequire one or more unique physical connection elements 412 in order tomount securely to the physical geography 414. In some embodiments, thephysical infrastructure elements 412 are removable fasteners, as shownin FIG. 4. In other embodiments, the infrastructure adapter 302 ispermanently connected to the setting 414 by means of non-removablephysical connection elements 412.

The infrastructure adapter 302 also comprises an adapter quick connectinterface 416. The adapter quick connect interface 416 is configured toconnect to a corresponding interface on the external unit 304, calledthe external unit quick connect interface 502 (FIG. 5A). The adapterquick connect interface 416 shown in FIG. 4 is a female connector, butin other embodiments the adapter quick connect interface 416 will be amale connector.

The adapter quick connect interface 416 includes an adapter powerinterface 418. In some embodiments, the adapter power interface 418includes neutral three phase and ground power interfaces. In someembodiments, the adapter quick connect interface 416 also includes anadapter data interface or transceiver 420. In some embodiments, theadapter data interface/transceiver 420 is hard wired, while in otherembodiments the adapter data interface/transceiver 420 is wireless. Insome embodiments, the adapter data interface 420 includes acommunication connector for long range communications (such as tocommunicate directly with the data network 120, FIG. 1). In someembodiments, the adapter includes a signaling interface 421 whichincludes a digital connector for short range communications (such as tocommunicate with the external unit). In some embodiments, the datainterface 420 transfers analog data while the signaling interface 421sends digital information. In some embodiments, the adapter quickconnect interface 416 includes one or more adapter guide mechanisms 422,such as alignment pins or sockets. The adapter guide mechanisms 422 areconfigured to mate with corresponding pins or sockets in the externalunit quick connect interface 502 to align it for connection with theadapter quick connect interface 416 to form good electrical contactsbetween the electrical and data connectors without damaging them. Insome embodiments, the adapter quick connect interface 416 also includescoupling mechanisms designed to compensate for tolerances, relievepotential misalignment, and allow relative motion between the adapterquick connect interface 416 and the external unit quick connectinterface 502. In some embodiments, the tolerance mechanisms allow a fewmillimeters of play in two or more dimensions between the adapter'squick connect interface 416 and the external unit's quick connectinterface 502.

In some embodiments, the infrastructure adapter 302 also includes memory424, which is connected to the signaling interface 421. In someembodiments, the memory 424 stores geographic and/or electrical topologyidentification information that is unique to the particularinfrastructure adapter 302 or component thereof, known as a geographicID 426. In some embodiments, the geographic ID 426 includes a streetaddress, longitude and latitude coordinates, GPS location, and/or anyother identifier of geographic location. The geographic ID 426 isdiscussed in more detail with respect to FIGS. 6A-6D. In someembodiments, the memory 424 is stored in a central location and includesgeographic IDs 426 for each of a plurality of infrastructure adapters302 connected thereto. For example, a single memory 424 may be utilizedby all of the infrastructure adapters 302 on a floor of a parkingfacility. In some embodiments, each infrastructure adapter 302 includesa CPU and other components. In other embodiments, the CPU and othercomponents are stored in a central location and used by a plurality ofinfrastructure adapters. In still other embodiments, the infrastructureadapter 302 is passive, and all computing technology for the charge spot106 is contained in the external unit 304. Thus, the infrastructureadapter's complexity and cost is kept relatively low. It is beneficialin many embodiments to keep the cost of an individual infrastructureadapter 302 significantly lower than the cost of the external unit 304because in many embodiments more infrastructure adapters 302 aredeployed than external units 304. In other words, more infrastructureadapters 302 are initially installed than is required by current demand.As demand increases, external units 304 are connected to those extrainfrastructure adapters 302, as is explained in more detail with respectto FIGS. 6A-6D.

By way of summary, the infrastructure adapter 302 includes power, data,and physical connection elements which are specifically designed tointerface with the local electrical power, data, and geographicrequirements of the place of deployment (i.e., they are designed toconnect to the deployment area infrastructure). The infrastructureadapter also includes an adapter quick connect interface 416 forconnecting with a number of different external units 304 to form acomplete charge spot 106. As such, the infrastructure adapter 302 isoptimized for many different deployment locations, while providing auniform interface for the external unit 304 (and thus for the vehicle).

FIGS. 5A-5B illustrate an external unit 304 of a charge spot 106 inaccordance with some embodiments of the invention. As stated above, thecharge spot 106 comprises two distinct components, which are theinfrastructure adapter 302 and the external unit 304, which are ofteninstalled at different times as will be explained in more detail withrespect to FIGS. 6A-6D.

The external unit 304 comprises an external unit quick connect interface502. The external unit quick connect interface 502 is configured toconnect to adapter quick connect interface 416 shown in FIG. 4. Theexternal unit quick connect interface 502 shown in FIG. 5A is a maleinterface, but in other embodiments the external unit quick connectinterface 502 will be female.

The external unit quick connect interface 502 includes an external unitpower interface 504. In some embodiments, the external unit powerinterface 504 includes neutral three phase and ground interfaces. Insome embodiments, the external unit quick connect interface 502 alsoincludes an external unit data interface 508. In some embodiments, theexternal unit data interface 508 is wired, while in other embodimentsthe data interface 508 is wireless. In some embodiments, the externalunit data interface 508 includes a communication connector for longrange communications (such as to communicate directly with the datanetwork 120, FIG. 1). In some embodiments, the external unit includes adigital connector for short range communications (such as to communicatethe geographic ID with the infrastructure adapter). In some embodiments,the data interface 508 transfers analog data while the digital connectorsends digital information. In some embodiments, the external unit quickconnect interface 502 includes one or more external unit guidemechanisms 510 such as alignment pins or sockets. The external unitguide mechanisms 510 are configured to align and mate with the adapterguide mechanisms 422. In some embodiments, the external unit quickconnect interface 502 also includes coupling mechanisms designed tocompensate for tolerances, relieve potential misalignment, and allowrelative motion between the adapter quick connect interface 416 and theexternal unit quick connect interface 502. In some embodiments, theexternal unit quick connect interface 502 is coupled to the rest of theexternal unit 304 by means of removable fasteners 512. In otherembodiments, the external unit quick connect interface 502 is integrallyformed with other portions of the external unit 304. The external unitquick connect interface 502 also has a car electrical connector 514. Thecar electrical connector 514 includes a variety of connectors configuredto electrically connect to the vehicle charging interface 206 (FIG. 2)for temporarily connecting to and charging the battery of an at leastpartially electric vehicle 102. The vehicle charging interface 206 isthe external portion of the car electrical connectors 514.

In some embodiments the external unit 304 includes a GFCI or residualcurrent device 515 that disconnects the circuit whenever it detects thatthe electric current is not balanced between the energized conductor andthe return neutral conductor for safety and handling reasons. In otherembodiments, the residual current device 515 is located elsewhere. Theexternal unit also includes circuit breakers 516. The circuit breakers516 are configured to protect the internal components of the charge spotand the vehicle from power surges and shorts. The external unit 304 alsoincludes an AC/DC power supply unit 517 and a computer system controller518 which is shown in detail in FIG. 5B. In some embodiments, theexternal unit 304 includes an optional contactor or AC switch 519 toturn off an on the AC electricity flowing to the vehicle duringcharging. In other embodiments, the contactor 519 is located outside theexternal unit. The external unit also includes a charging interface 206(such as an outlet or cable) as explained in FIG. 2, for connecting tothe vehicle. Furthermore, the external unit may include a man/machineinterface 521. In some embodiments, the man/machine interface 521includes a physical user interface with a screen and keyboard. In otherembodiments, the man/machine interface 521 comprises only wirelesscommunication capabilities such as blue tooth, GSM, and RFID. In someembodiments, the external unit also includes one or more meter units(not shown) to control and/or determine the power being sent to thevehicle.

FIG. 5B is a block diagram illustrating the computer system controller518 of a charge spot 106. In most embodiments, all of the components ofthe computer system controller 518 are located in the external unit 304of the charge spot, while in other embodiments at least some of thecomputer system controller 518 components are located in theinfrastructure adapter 302.

The computer system controller 518 typically includes one or moreprocessing units (CPU's) 520. The computer system controller 518includes one or more network or other communications interfaces 524 thatcommunicate with the contactor 519, the vehicle 102, the infrastructureadapter 302, and/or include direct communication mechanisms (e.g.,antennas, I/O interfaces, etc.) The computer system controller 518includes memory 522, an optional positioning system 560 that determinesand/or reports the position of the charge spot 106, a DC/DC power supplyunit 562 used to provide power to the computer system and/or othercomponents within the charge spot, sensors 564 that monitor the internalcomputer system temperature, actuators 563 that lock a charginginterface 206 with the vehicle, and one or more communication buses 526for interconnecting these components.

The charge spot 106 optionally may include a user interface 528comprising a display device 530 and input devices 532 (e.g., a mouse, akeyboard, a touchpad, a touch screen, etc.). In other embodiments,communications with the charge spot 106 are performed with input devicesin the vehicle 102 or are controlled by the service provider 112 via thedata network 120 (see FIG. 1).

The memory 522 includes high-speed random access memory, such as DRAM,SRAM, DDR RAM or other random access solid state memory devices; and mayinclude non-volatile memory, such as one or more magnetic disk storagedevices, optical disk storage devices, flash memory devices, or othernon-volatile solid state storage devices. The memory 522 may optionallyinclude one or more storage devices remotely located from the CPU(s)520. For example, in some embodiments, some or all of the components ofmemory 522 are housed in a central memory that controls a group ofcharge spots 106. The memory 522, or alternately the non-volatile memorydevice(s) within memory 522, comprises a computer readable storagemedium. In some embodiments, memory 522 stores the following programs,modules and data structures, or a subset thereof:

-   a board support package 533 for supporting the computer system    controller 518 hardware platform;-   an operating system 534 that includes procedures for handling    various basic system services and for performing hardware dependent    tasks;-   a communication module 536 that is used for connecting the charge    spot 106 to other computers via the one or more communication    network interfaces 304 (wired or wireless) and one or more    communication networks, such as the Internet, other wide area    networks, local area networks, metropolitan area networks, and so    on;-   a user interface module 538 that receives commands from the user via    the input devices 532 (or the vehicle's input devices) and generates    user interface objects in the display device 530;-   a positioning module 540 that determines and/or reports the position    of a charge spot 106 using an optional positioning system 560 or the    geographic ID 426 from the infrastructure adapter 302 as described    herein;-   a charging control module 542 that determines and reports the status    of the charge spot 106 and that performs operations related to    charging batteries 104 at a charge spot 106;-   an optional account module 544 that manages account information of    users of vehicles;-   a remote management module 546 which allows remote control of the    charge spot.

Each of the above identified elements may be stored in one or more ofthe previously mentioned memory devices, and corresponds to a set ofinstructions for performing a function described above. The set ofinstructions can be executed by one or more processors (e.g., the CPUs520). The above identified modules or programs (i.e., sets ofinstructions) need not be implemented as separate software programs,procedures or modules, and thus various subsets of these modules may becombined or otherwise re-arranged in various embodiments. In someembodiments, memory 522 may store a subset of the modules and datastructures identified above. Furthermore, memory 522 may storeadditional modules and data structures not described above.

For the purpose of staged deployment, in most embodiments, the externalunit 304 includes at least a processing unit 520 and memory 522 whichcommunicates with the adapter's memory 424 to obtain and store thegeographic ID 426. The external unit 304 also contains a communicationsinterface 524 which communicates with the data network 120 (FIG. 1). Insome embodiments, the geographic ID 426 is used during charging toidentify which charge spot 106 is transferring power. Furthermore, whenthe charge spot 106 fails or malfunctions, the geographic ID 426 is sentby the communications interface 520 to the data network 120 along with arequest for maintenance.

In most embodiments, the external unit also contains a charging controlmodule 542 configured to regulate the power supplied to the vehicle 102.In some embodiments, the charging control module 542 will step down thesupplied power to the requirements of the vehicle. The power componentsof the infrastructure adapter 302 and the external unit 304 areconfigured to transmit high voltage and current electrical energybetween the charge spot 106 and the vehicle 102. High voltage is definedas anything above one kilowatts. In some embodiments high voltage poweris defined as ranging from one kilowatts to 40 kilowatts. The particularvoltage and current capacities of the power components of theinfrastructure adapter 302 and the external unit 304 will vary dependingon the particular energy needs of the application. For instance, highperformance vehicles may require a higher voltage or current carryingcapacity than standard vehicles, and thus specialized high capacitycharge spot 106 may be used.

FIGS. 6A-6D are pages of a multi-page flow chart representing themethods of deployment and replacement of charge spots according to someembodiments of the invention. Some portions of the flow chart encompassthe method of staged deployment of an electrical charge spot system. Insome embodiments, the electric charge spot system includes only onecharge spot 106, while in other embodiments the electrical charge spotsystem includes a plurality of charge spots. Some portions of the flowchart encompass deploying various portions of the charge spots instages. Some portions of the flow chart encompass obtaining andcommunicating a geographic ID for the charge spot 106. Some portions ofthe flow chart also encompass replacing at least a portion of the chargespots.

As shown in FIG. 6A, one or more infrastructure adapters 302 areinstalled (602). In some embodiments, the installing includes accessinga power source (604). In some embodiments, the data source is alsoaccessed when the power source is accessed. In most embodiments, thiswill require shutting down at least the portion of the power sourcewhere the infrastructure adapters 302 are to be installed, possiblyshutting down nearby buildings as well. The installation may alsoinvolve demolition or partial demolition of a wall, floor, or ceiling(606). It may involve excavation. Installation may involve trenching tolay down power cables which may be located under a sidewalk, road, orbuilding. The installation of the infrastructure adapter 302 may alsoinclude re-building the infrastructure (608). Rebuilding may involvepatching the wall, floor, or ceiling, placing a structural foundationfor the infrastructure adapter, and leveling. Thus, demolishing andrebuilding of the infrastructure are both aspects of installing theinfrastructure adapters along with physically mounting or attaching theinfrastructure adapter 302 to its physical location after theinfrastructure adapter 302 has been connected to the power source. Forexample, in some embodiments, the power source and data sources areaccessed, the structural foundation is placed, the power and optionalcommunication cables are threaded through the foundation, and then thefoundation is backfilled, and the infrastructure adapter is mounted inthe infrastructure installation. The installing may also includecovering the infrastructure adapter with a temporary housing (610). Inmany embodiments, the installation of the adapters is relatively timeconsuming and costly because accessing or deploying the power lines tothe power source may be costly and time consuming. As such, in manyembodiments, once the power source has been accessed, a plurality ofinfrastructure adapters 302 is installed. In some embodiments, theadapters are overbuilt, i.e., more infrastructure adapters 302 areinstalled during the initial installing stage than are immediatelyrequired. In this way, the infrastructure adapters 302 will already bein place when the demand for charge spots increases. The specifics ofthis are explained below. It should be noted that because moreinfrastructure adapters 302 are installed than are required, theinfrastructure adapters 302 are relatively inexpensive, as compared tothe external unit 304 portion of the charge spots. This helps reduce thecost of initial deployment.

Once the power source is accessed, the infrastructure adapter 302 iscoupled to it (612). Specifically, the power supply electrical interface402 of the infrastructure adapter 302 is coupled to the power supply. Insome embodiments, the coupling further includes testing theinfrastructure adapter to make sure it is working properly.

In some embodiments, the geographic location of the infrastructureadapter 302 is obtained (614). The geographic location may be obtainedin a variety of ways. For example, it may be pre-assigned or it may bedetermined using a global positioning system device. In someembodiments, the geographic location is ascertained with a GPS used by askilled operator at the time of installation, and includes longitude andlatitude coordinates (616). In some embodiments, the geographic locationis one or more of a local city, street, house number, or space number, amile marker number (618). As shown in FIG. 6B, in some embodiments, thegeographic location is recorded into the infrastructure adapter as ageographic ID (620). In some embodiments, the geographic ID is hardcoded while in other embodiments it is soft coded into theinfrastructure adapter (621). In some embodiments, the geographic IDincludes a variety of information besides just location. In someembodiments the geographic ID includes electrical topology information(622), such as the number of charge spots at a particular location, thesequential number of the charge spot at that location, the power supplyoffered at that location, etc. Electrical topology information can beused for grid management, maintenance, and unique charge spot (oroutlet) identification.

In some embodiments, the geographic ID is unique to the infrastructureadapter 302 into which it is coded (623). In some embodiments, thegeographic ID is stored in the memory of the infrastructure adapter. Insome embodiments, the geographic IDs of each infrastructure adapter in afamily of interconnected infrastructure adapters 302 are stored in acentral on-site location (624). For example, memory (i.e., a locationcontroller) associated with a respective infrastructure adapter 302 maybe used by a plurality of infrastructure adapters 302 that are alllocated near each other such as in the same row of parking spaces or onthe same floor of a parking structure. In some embodiments, somegeographic ID information is stored in the location controller whileother geographic ID information is stored in the infrastructureadapter's device memory. In some embodiments, a variety of geographicIDs is stored for particular elements of the infrastructure adapter orfamily of adapters. In some embodiments, geographic IDs include one ormore of a panel geographic ID, a circuit geographic ID, a charge spotgeographic ID, and a socket geographic ID (625). In some embodiments thepanel geographic ID and circuit geographic ID is stored in the locationcontroller while the charge spot geographic ID and socket geographic IDis stored in the charge spot.

In some embodiments, the geographic ID is broken into two types: site IDwhich is geographical, and electrical device ID which is topological(626). In some embodiments, the site ID includes one or more of thefollowing: Country (Country code according to International subscriberdialing codes); Region (such as state or territory): Sub-region 1 (suchas city); Sub-region 2 (such as city district); and site number(specific to the site or building address.) In some embodiments theelectrical device ID includes one or more of the following: Panelnumber, circuit number, charge station number (identifying theparticular charge station); and outlet number (used when a chargestation has a plurality of charging interfaces to charge more than onevehicle simultaneously). As such

-   Panel: Country-Region-Subregion1-Subregion2-SiteNumber-Panel-   Circuit:    Country-Region-Subregion1-Subregion2-SiteNumber-Panel-Circuit-   CS:    Country-Region-Subregion1-Subregion2-SiteNumber-Panel-Circuit-Charge    Spot-   Socket:    Country-Region-Subregion1-Subregion2-SiteNumber-Panel-Circuit-Charge    Spot-Socket

As shown in FIG. 6C, during a second stage, the external unit 304 isinstalled (628). The installation may be performed by a different andlikely less skilled operator than the operator that installed theinfrastructure adapter. The installing may include physically securing ashell over the external unit 304 and the infrastructure adapter (630).For example, in some embodiments, the shell is secured to a wall, floor,or ceiling, or to the base of an infrastructure adapter 302 by means ofone or more fasteners as discussed with respect to FIG. 2. Theinstalling also includes mating the external unit quick connectinterface 502 to the adapter quick connect interface 416 (632). (Itshould be noted, that in most embodiments the quick connectors are matedprior to securing the shell.) As such, the external unit 304 isremovably coupled to the infrastructure adapter. The mating forms anelectrical connection between the external unit quick connect interface502 and the adapter quick connect interface (634). In most embodiments,these interfaces are standard such that any external unit 304,regardless of shape, can be coupled to nearly any infrastructureadapter. In most embodiments, the mating can be completed quicklybecause the interfaces are standard and are designed to fit togetherquickly and easily. For example, in some embodiments, the only toolrequired is a screwdriver. Furthermore, in some embodiments the matingrequires only lifting the external unit 304 into position above theinfrastructure adapter and then sliding the external unit's quickconnect interface into the adapter's quick connect interface. No wiringis required to mate the two pieces together. In some embodiments, themating is concluded in under 5 minutes (636). Furthermore, the skilllevel required for installing the external unit 304 is relatively low.Thus, the cost of installation is also low because a skilled operator isnot necessary. In some embodiments the installing of the external unitfurther includes testing the external unit to make sure it is workingproperly.

In some embodiments, after the external unit 304 has been installed, thegeographic ID is communicated from the infrastructure adapter 302 to theexternal unit (638). In some embodiments, the geographic ID is stored inmemory located in the external unit 304. In some embodiments, thegeographic ID is used by the external unit 304 during the vehiclecharging process (640). For example, the geographic ID may becommunicated to the vehicle so that the vehicle can communicate thegeographic ID to the service provider. In some embodiments, thegeographic ID is also communicated to the data network 120 either viathe vehicle or directly from the infrastructure adapter. In someembodiments, the service provider tracks which charge spots and forcharge spots with multiple charging interfaces, which charging interface206 on the charge spot are providing power.

As shown in 6C, the geographic ID is communicated to the serviceprovider (642). In some embodiments, other information is also passed tothe service provider, such as charge information associated with powerthat is flowing from the charge spot 106 to a vehicle. In someembodiments, the geographic ID is communicated directly from theinfrastructure adapter, while in other embodiments it is communicated bythe external unit 304, or through the vehicle (644).

As shown in FIG. 6D, in some embodiments, the method continues withproviding power from the power source to the vehicle through the chargespot (646). Specifically, the vehicle is temporarily coupled to vehiclecharging interface 206 of the car electrical connector 514. Then poweris enabled such that it flows from the power supply to the vehiclethrough the power supply electrical interface 402, the adapter quickconnect interface 416, the external unit quick connect interface 502,and the car electrical connector 514. A more detailed explanation of thecharging of an electric vehicle by a charge spot 106 is discussed inapplication Ser. No. 12/560,337 herein incorporated by reference in itsentirety.

In some embodiments, an external unit 304 is replaced with a newexternal unit (648). In some embodiments the new external unit isinstalled to upgrade the unit. For example, new development in the fieldor upgraded standards may be the reason that a new external unit isinstalled. In some embodiments, the replacement is initiated because theoriginal external unit 304 malfunctions (650). In some embodiments, whenthe external unit malfunctions, the external unit 304 or theinfrastructure adapter 302 reports the malfunction and the geographic IDof the charge spot 106 to the service provider (652). As such, theservice provider knows exactly which charge spot 106 requiresmaintenance. In some embodiments, the replacing includes decoupling theexternal unit quick connect interface 502 of the respective externalunit 304 from the adapter quick connect interface 416 of the respectiveinfrastructure adapter, and removably coupling an external unit quickconnect interface 502 of the new external unit 304 to the adapter quickconnect interface 416 of the respective infrastructure adapter (654). Insome embodiments, each of the decoupling and coupling of the replacementtake place in under 5 minutes (656). In some embodiments, the decouplingand re-coupling can happen quickly because the only tool required is ascrewdriver. Furthermore, in some embodiments the decoupling requiresonly removing the charge spot shell and lifting the external unit 304then sliding the external unit's quick connect interface out of theadapter's quick connect interface. It should be noted that other stepsmay be involved in the replacement, such as taking off the shell of theexternal case. These other steps are not included in the 5 minutes notedfor the de-coupling and coupling. In some embodiments, the replacingalso includes communicating the geographic ID (likely stored or hardcoded into the infrastructure adapter 302) to the new external unit(658). Because of the ease of de-coupling an old external unit 304 andcoupling a new external unit 304 to the infrastructure adapter, the costof maintenance is kept low. Specifically, an operator with special skillis not required for the replacement. The malfunctioning external unit304 can be taken back to a central location where a skilled operator canin some cases fix and re-furbish it for future use.

In some embodiments, when demand for electrical charge spots increasesmore external units 304 are installed to already installedinfrastructure adapters (660). Specifically, additional external units304 are installed by removably coupling the additional external unitquick connect interfaces 502 of the additional external units 304 toadapter quick connect interfaces 416 of previously unused infrastructureadapters. The installing of additional external units does not interferewith the operation of the charge spots already in operation. As such,the electrical charge spot 106 system is designed for staged deploymentthat is easy to scale. The scaling can be done over a period of time asdemand for charge spots increases. By installing more, relativelyinexpensive infrastructure adapters 302 during the infrastructureinstallation, the underlying infrastructure such as the street orbuilding holding the parking spots need only be disturbed once. Then theexternal units 304, are not installed until demand requires them. As theexternal units 304 are the more complex and thus more expensive portionof the charge spot 106, the cost of deployment also scales with demand.
